The DAC

The TauDAC-DM101 is a ultra-high performance I2S DAC module for the Raspberry Pi. It uses two outstanding WM8741 DAC-chips in dual-mono mode and ultra-low phase noise clocks. The DAC-Chips and the clock oscillators are driven by separate, ultra-low noise, high PSRR power supplies.

The Output Stage

The TauOUT-TP101 is a high performance passive output stage for the TauDAC-DM101. The module features Lundahl transformers for summing the differential outputs of the DACs as well as for galvanic isolation.

Features

galvanic isolation between the left and the right channels as well as between the DAC and the power amplifier

greatly improves immunity to external noise sources

High-quality massive RCA connectors:

non-magnetic, eutectic brass, rhodium over silver plate

Shielded DC power connector:

main power supply for the Raspberry Pi and the DAC

The RCA and the DC power connectors are at the same side as the USB and Ethernet connectors of the Raspberry Pi — the assembly can be build into a case with all required connectors at back panel.

The Power Supply

The TauOUT board provides a DC power jack. You need a single 6.3 – 9.1VDC power supply to power the Raspberry Pi and the TauDAC through the TauOUT board. The power supply should be able to provide at least 1.5A. The DC power jack center pin has a diameter of 2 mm. It is not necessary (and not recommended) to connect an external power supply via USB to the Raspberry Pi.
